The scripts were named the same for syslinux and grub. Because of this,
scripts for syslinux were overwritten by grub scripts.

NetworkManager not worked without udev-rule-generator-net on sysvinit

Many applications need a gnome-icon-theme.

Нужно признать, что grub станларт, которму мы должны соответствовать.
а поддержка efi у нас полноценна пока только в refind.

Also added explicit call +sysvinit or +systemd for server targets.
Users also want to start the server on systemd.
in addition to on aarch64 in qemu, the shell does not start on the
serial console for sysvinit. This is critical for non-desktop builds.

.regular-sysv -> .regular-desktop-sysv
.regualar-sysv-gtk -> regular-gtk-sysv

- replace easypaint in desktop+lxqt, builded with qt5
- cleanup qt4 applications
- drop cool-retro-term (it is certainly cool, but not required)
- clementine allowed for all platforms

After switching to these symlinks, you no longer need to create
the missing directories.

Not needed for polkit-sysvinit >= 0.4

This one has filled up the entire 8 Mb tmpfs
while running inside installer stage1 on a
124-drive system (configured as JBOD).

...for zgrep and friends; might be worth including into
distros proper by default.

Still commented out, though; maybe someone pays attention later on.

fwupd needs python3-module-pygobject3 which requires graphics libraries
(unacceptable for the basic rescue images).

Install /etc/*-release files if needed.

Make it uniform through a function -- with the initially desired effect
of no extra lines while building multiple images with REPORT=1
(those were useless anyways printing repeatedly the same path
that's relative to a particular builddir).

...as cloud-init will do that.

The case at hand was the need to pass serial console parameters,
see the next commit.

mpv is not needed in every single one of those images.

autofs4.ko is not available on Tavolga, and might be unavailable
elsewhere as well (or vice versa, might become available).
